Working Principle

1. Three-phase sine wave excitation current supplied by matched 230VAC low-voltage servo drive energizes stator long-stack distributed winding to generate stable high-strength rotating magnetic field;
2. Interior permanent magnet rotor interacts with stator rotating field to produce sustained high electromagnetic torque transmitted through output shaft to mechanical load;
3. Rear-mounted analog resolver converts mechanical rotation angle and rotational velocity into analog voltage feedback signals, transmitted back to servo drive to form full closed-loop speed and position regulation;
4. Extended long stator stack design expands effective magnetic contact area to raise continuous torque output without enlarging flange installation footprint;
5. Vacuum-impregnated winding structure eliminates internal air gaps to reduce heat accumulation during full-load continuous duty cycle operation.

Function Features

1. Long-stack electromagnetic design delivers elevated continuous torque output ideal for low-speed steady rotation heavy-load axes;
2. Analog resolver feedback maintains stable signal transmission under severe vibration, wide temperature fluctuation and oil mist industrial environments with zero signal attenuation;
3. Low cogging torque lamination layout restricts torque ripple <1.4% across the entire operating speed range to achieve ultra-smooth constant-speed operation;
4. Class F high-temperature winding enables stable continuous operation within ambient temperature range -20°C ~ +40°C;
5. Sealed bearing structure delivers 20,000 rated operating hours maintenance interval without intermediate grease replenishment.

Advantage Highlights

1. Long-stack frame provides significantly higher continuous torque output compared to medium B-204/B-206 models while retaining standardized NEMA mechanical flange interface;
2. Thick aluminum alloy housing delivers excellent thermal conductivity to suppress winding temperature rise under long-duration full-load operation;
3. Vibration-resistant resolver feedback eliminates fragile optical encoder glass elements, eliminating failure risks in metal cutting and stamping workshop environments;
4. Full compatibility with all Kollmorgen CE06 low-voltage and AKD single/three-phase servo drives, no manual motor parameter calibration required after wiring connection;
5. Universal NEMA 34 flange mechanical interface supports direct drop-in replacement for all mainstream large-frame medium-torque servo motor brands globally.

Applicable Industries

Installation Requirements

1. NEMA 34 four-hole square flange mounting; M10 high-strength bolts crosswise evenly tightened to 18N·m torque to eliminate uneven flange mechanical stress;
2. Minimum clearance of 40mm surrounding motor heat sink fins to guarantee unobstructed natural convection airflow circulation;
3. Shaft coupling radial concentricity runout error strictly controlled ≤0.04mm to avoid accelerated bearing fatigue and premature failure;
4. Rear cable junction box must be positioned upward or horizontal orientation to prevent liquid coolant accumulation inside wiring terminal chamber;
5. Mounting base flatness tolerance ≤0.06mm over the complete flange contact surface; uneven base surface generates continuous side load on motor bearings;
6. Flexible bellows shaft coupling is mandatory for reciprocating motion axes; rigid direct connection between motor shaft and load shaft is prohibited.

Usage Precautions

1. Cease equipment operation for passive cooling if motor housing external surface temperature exceeds 90°C; maximum safe continuous winding operating temperature is 130°C;
2. Direct radial impact force cannot be applied to output shaft during mechanical assembly; impact deformation of bearing inner race leads to irreversible bearing noise and wear;
3. Long-term continuous operation within mechanical resonance speed band of 900–1500 RPM is forbidden to avoid excessive vibration and structural fatigue;
4. After reaching 20,000 continuous rated operating hours, bearing grease replenishment maintenance must be performed;
5. High-pressure water jet direct washing of rear resolver feedback cover and power junction box is strictly prohibited to prevent water ingress damage to internal electrical components;
6. This motor model is exclusively matched with 230VAC low-voltage servo drives; connection to 380–480V high-voltage drives causes immediate irreversible stator winding insulation burnout.
